thank you i should have mentioned that i have opened it up and removed both upper and lower agittator and the dogs are worn out my problem is in the shaft not sure if its transmision it runs fine untill the SPIN CYCLE reaches top speed is when the lower agittator or shaft starts and stops abrubtly making a loud CLUNK CLUNK CLUNK o meanwhile the tub trys to stay at speed

Bad transmission. The agitate cam is likely worn and not fully disengaging agitate gear during spin. The noise is the internal splines of the agitate gear hitting the splines on the spinning agitator shaft. Transmission can be repaired if you want to take it apart.

You only have to remove the agitator to pull the gearcase. If the agitator has a fabric softener dispenser, there will be a clip on the agitator shaft and a plastic washer below it that must be removed as well. Clamp the gearcase in a level position as there is 16oz of oil in it. There is no formed gasket so you will need to use a putty knife to get the gearcase cover off. Thorougly clean the mating surfaces and use form a gasket when putting it back together. Pull the small spin pinion gear off the agitator shaft. Remove the clip holding the large spin gear on and remove gear. Lift the three parts off the plate below the gear. Remove the spin pawl stud and remove the plate. Remove connecting rack and shift actuator. Now you can pull the agitator shaft. Don't lose the thrust washer and ball in the hole where the shaft was. Clamp shaft upside down in vise and remove lower retaining clip. You can push down on the agitate gear and rotate it a bit so that the splines keep tension off the retaining clip. Remove cam and cam follower and replace with new parts. Reassemble and you should be good to go. Make sure tangs on shifter are not bent. Good luck.

At time 3:26 in the video where he starts showing the agitator shaft, the one he is showing is not the one from that transmission and the cam and cam follower are on that shaft in reverse order. He got it wrong, and it's not going to work if you follow his directions. Pay attention to how your parts come off so you get them back in proper order. Cam follower goes on first, then cam.

What happens is, the ramps in the cam and cam follower wear so that when in spin mode and the cam is rotated by the shift actuator so that the ramps are engaged, the agitate gear is not lifted far enough to completely disengage it from the splines on the agitator shaft. Replace the cam parts.
